Battery module heating collection device, battery module and vehicle

Abstract

The invention discloses a battery module heating acquisition device, a battery module and a vehicle. The battery module heating acquisition device comprises a device body and a collecting element, andthe device body is of a sheet structure. The device body is attached to any side face, not provided with the electrodes, of the battery module. The device body comprises a circuit area and a heatingarea. The circuit area is located on the periphery of the heating area and provided with a plurality of collecting terminals, the collecting terminals extend to the side, provided with the electrodes,of the battery module, the collecting element is electrically connected with the collecting terminals, the collecting element and the electrodes are arranged on the same side, and the collecting element comprises a voltage collecting piece, a pressure sensor and / or a temperature sensor. The circuit area and the heating area are integrally arranged on the device body, so that the occupation of theinternal space of the battery membrane group can be reduced. Through arrangement of the circuit area, connecting wires of all the collecting elements in the battery module can be integrated into thecircuit area to be arranged in a unified mode, and therefore the messy problem and space occupation caused by circuit arrangement of the collecting elements are avoided.

Description

technical field [0001] The invention relates to the technical field of battery structures, in particular to a battery module heating and collecting device. Background technique [0002] Electric vehicles are powered by vehicle-mounted power supplies, driven by motors to drive wheels, and meet the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic. The key core component of electric vehicles is the power battery, whose performance and cost directly affect the smooth progress of large-scale promotion and application of electric vehicles. Due to the advantages of high power density, high energy density and long service life of lithium-ion power batteries, it has become the most important power source for the development of new energy vehicles. [0003] However, the energy provided by a single battery is limited. To meet the electric energy demand of electric vehicles or e...

AI Technical Summary

Problems solved by technology

However, the acquisition module, temperature acquisition module, pressure acquisition module, and heating device are installed in the battery module, which makes the data monitoring and acquisition wiring harness of the battery module messy, unplanned, unfixed, and unprotected, and the wiring harness is very vulnerable to wear and tear. Extrusion leads to insulation failure, and it is easy to cause short circuit of wiring harness due to misoperation during production. The reliability is very poor, and it is troublesome to remove and maintain.
